Wisconsin River Partners

What Wisconsin River Partners does

Wisconsin River Partners (WRP) is a private investment and operating firm headquartered in Wausau, Wisconsin (500 N. 1st Street, Suite 2600) that acquires and grows lower middle-market manufacturing and industrial companies based in Wisconsin. The firm invests its own capital alongside accredited co-investors into succession-driven or growth-capital targets, operates each portfolio company under retained local leadership, and reinvests 10% of profits into Wisconsin community organizations. Its current portfolio spans at least four verticals: Profile Finishing Systems (custom surface preparation and liquid coatings, acquired 2018, two Wisconsin facilities), Lemke Industrial Machine (specialized machinery for locks, dams, and moveable bridges, acquired 2020, Wausau), Witmer Furniture (premium solid-wood furniture, acquired 2021, near Wausau), and PROOF., a consolidated commercial-printing platform formed from the 2023 acquisitions of Sun Printing and Heyrman Printing and the 2024 acquisition of Delzer Lithograph, with locations in Wausau, Green Bay, and Waukesha.

The business model is return-driven rather than fee-driven: WRP does not appear to operate a traditional third-party fund structure, instead deploying its own balance sheet capital and raising co-investment directly from individual accredited investors. Returns are realized on exit as the spread between acquisition price and exit value, with value creation sourced from capacity expansion (new equipment, facility buildouts), talent additions, operational systems (e.g., an MIS tool at PROOF.), and revenue growth reported by portfolio company leadership. The firm has roughly five management team members (Co-Founders Jim Frings and Kevin Kraft, Director Ted Kemen, Portfolio Company CFO Crystal Kirchner, and Business Analyst Joe DeLoye) supported by a five-member advisory board.

The go-to-market is relationship-driven and geographically narrow: sourcing flows from direct outreach to Wisconsin business owners considering succession, referrals from local professional advisors (attorneys, accountants, bankers), and community networks cultivated over decades of operating locally. Marketing channels are de minimis — a Squarespace-hosted website, an investor portal, and community presence — with no digital demand generation, public pricing, or investment minimums disclosed. Kevin Kraft ([email protected], 715-841-0084) serves as the primary contact for both sellers and prospective investors.

Revenue model

1. Investment Returns from Portfolio Companies: Wisconsin River Partners generates returns through acquiring manufacturing and industrial companies, improving their operations and financial performance, and ultimately selling or exiting these businesses. Returns come from the difference between acquisition cost and exit value, driven by operational improvements, revenue growth, and strengthened cash flows. As an investor that puts its own capital into every deal, returns are realized upon successful exit of portfolio companies.
